Letters Patent No. 62,964, dated March 19, 1867.

IMPROVEMENT IN METAL CLASPS FOR BARREL HOOP S. I

To ALL WHOM IT MAY CONCERN: g

1 .Be itknown that I, DAVID M. LAWRENCE, of thecity of Washington, District of Columbia, have invented a new and improved Fastening for Metallic Hoops used in hooping vessels; and I do hereby declare the follow-' ing to be a full, clear, and exact description of the same, suilicient to enable one skilled in the art'to which this invention appertains-to make use of it,'reference being had to the accompanying drawings, which form a. part of this specification, and in which 1 'Figure 1 is a perspective view. i

Figure 2 is a view of the side of the fastening next the barrel.

Figure 3 is an edge view of the fastening.

The object of my lnvention 1s for the purpose of facilitating the adjustment of" mctallichoops on cisterns, casks, barrels, kegs, tubs, or other vessels on which metallic hoops are used, being a great improvem'ent over the ordinary mode of fastening with rivets, which necessitates the cutting away a portion of the hoop, thereby greatly impairing itsstreng'th, and rendering it liable to tear or break out at that point. The fastening which is the means of uniting the ends of the hoop is a solid piece of metal with a slotted or loop opening, which opening may be square or tapering, with a shoulder or shoulders above or below, on one or both sides, as may be required to facilitate the driving of the hoop, and to prevent its becoming embedded in the stares. The side-bars may be flat' or oval on one or both sides, and may taper to the'outer edge, the inner edge of which may be square or rounding. g I I In the drawing, A represents the fastening on the'barrel, showing the slot B. E represents the hoop, the ends of which having been previously looped inward over the bars d, and fitted into thebed between the shoulders c, is then driven over the barrel. The plate or buckle is a thin solid piece of brass or other metal, with a slotted or loop opening to admit the ends of the iron hoop, and made with shoulders at each end of the slot or opening, of a thickness equal to the thickness of thehoop, to facilitate the driving of the hoopon the barrel, and to prevent its becoming embedded in the staves. There is also on. one of these shoulders a flange or tongue, 0, which, becoming embedded in the wood, prevents the hoop from slipping or moving fromits position.

What I claim as my invention, and desire to secure by Letters Patent, isi The buckle or plate A, with its slotted or loop opening to receivethe. iron hoop, and with shoulders, c c, at each end, together with the tongue or flange, substantially as set forth in the foregoing specification, and for the purposes therein indicated. I l DAVID M, LAWRENCE.
